What it is
xCoin is a proof-of-work coin. Ticker XID. Mainnet started September 26, 2026, 00:00 UTC. Rules were frozen at genesis.

Every spend is signed with ML-DSA-65 (NIST FIPS 204) from block 1. SLH-DSA-SHA2-128s is also valid. There is no classical signature type on this chain. Node connections use hybrid ML-KEM-768.

Read the repos before you run binaries. Build from source if you can. Do not paste a seed into mining software.

Mining
Algo is MetalDAG: memory-hard, 4 GiB dataset, dataset grows 128 MiB every 14-day epoch. The bottleneck is memory bandwidth, not a warehouse full of cheap hash chips.

That is why they point at machines people already have, especially Apple Silicon: MacBook Air, MacBook Pro, Mac mini, Mac Studio, iMac. Unified memory is the point. Project docs say 16 GB RAM or more for the 4 GiB DAG; an 8 GB Mac is not a good fit.

Recommended miner is MMM.

The project site shows a live M3 Pro session around 8.61 MH/s. Your number depends on the machine, heat and power mode.

Coinbase matures after 1,000 blocks, about 3.5 days at 5-minute blocks.

Money rules
• Cap: 100,000,000 XID, 8 decimals, enforced every block
• No premine, no founder allocation, no sale
• Warm-up: 6.25 / 12.5 / 25 XID per block, 20,000 blocks each
• Then 50 XID per block from block 60,001 to 220,000
• After that, 10% less every 110,000 blocks (~382 days)
• Floor 1.5 XID per block for a long stretch, then a fade. Last coin around 2363
• Schedule hash is committed in genesis. Anyone can add the table up to the cap

Genesis
Block 0 mints nothing. Coinbase carries the charter hash.

Who runs the software
Distributed Ledger Technologies (Passaic, NJ) ships the reference code and public infra. They say they do not sell coins, do not list XID, and have no admin key that can freeze or reassign coins. Rule changes need a protocol upgrade that node operators choose to run.

• Self-custody account UI: https://xalon.com
• Spot market (separate site, one pair XID/USDC): https://ayedex.com

That last one is an exchange with its own rules and fees. Not required to use the coin.

No price talk from me. If you mine, check the explorer first and confirm you are on mainnet. A 16 GB+ MacBook or Mac mini is a reasonable place to start; it is not a promise that your electric bill will love you.
